Variable Flow Static Mixer

December 1, 2011

A variable flow static mixer for any fluid handling system that automatically adjusts to hold the head loss constant over 80 percent of the flow range is available from Westfall Manufacturing Company of Bristol, R.I. The Westfall Model 2900 Variable Flow Static Mixer optimizes mixing and minimizes head loss by employing two in-line wafer type mixers, one fixed and one variable, which adjust incrementally to maintain constant head loss. Providing consistent mixing over a 20:1 turndown ratio, this mixer reduces overall system head loss at high flow rates and permits the use of smaller pumps, according to the manufacturer.
